NAME

       ncpdq - netCDF Permute Dimensions Quickly, Pack Data Quietly...

SYNTAX

       ncpdq  [-3]  [-4]  [-6] [-A] [-a dim[,...]]  [-C] [-c] [-D dbg] [-d dim,[ min][,[ max]]] [-F] [-h] [-L dfl_lvl] [-l path] [-M pck_map] [-O]
       [-o output-file] [-P pck_plc] [-p path] [-R] [-r] [-t thr_nbr] [-v var[,...]]  [-X box] [-x] input-file [ output-file ]

DESCRIPTION

       ncpdq packs or re-shapes variables in input-file and stores them in output-file.  Which variables to  pack/unpack  are  determined  by  the
       packing	policy	encoded  in  the  pck_plc  argument  to the -P switch.	Valid pck_plc options are all_new, all_xst, xst_new, and upk.  The
       numeric type of variable to pack or re-pack a variable to is determined by the packing map encoded  in  the  pck_map  argument  to  the	-M
       switch.	Valid pck_map options are flt_byt, flt_sht, hgh_byt, hgh_sht, and nxt_lsr.

       ncpdq  re-shapes variables in input-file by re-ordering and/or reversing dimensions specified in the dimension list.  The dimension list is
       a comma separated list of dimension names, optionally prefixed by negative signs, that follow the -a switch.  To re-order  variables  by  a
       subset  of  their  dimensions,  specify these dimensions in a comma-separated list following -a, e.g., -a lon,lat.  To reverse a dimension,
       prefix its name with a negative sign in the dimension list, e.g., -a -lat.  Re-ordering and reversal may be performed simultaneously, e.g.,
       -a lon,-lat,time,-lev.

       Users  may  specify any permutation of dimensions, including permutations which change the record dimension identity.  The record dimension
       is re-ordered like any other dimension.	The record dimension is always the most slowly varying dimension in a record variable.	The speci-
       fied re-ordering will fail if it requires creating more than one record dimension amongst all the output variables.

       The full documentation for NCO is maintained as a Texinfo manual called the NCO User's Guide.  Because NCO is mathematical in  nature,  the
       documentation includes TeX-intensive portions not viewable on character-based displays.	Hence the only complete and authoritative versions
       of   the   NCO	User's	 Guide	 are   the   PDF   (recommended),   DVI,   and	 Postscript   versions	 at   <http://nco.sf.net/nco.pdf>,
